摘　　要：针对感应耦合式电能传输(ICPT)系统中的信号反向(即从系统的副边向原边传输信号)传输问题,提出一种基于反射阻抗调制的信号反向传输方法。该方法根据被传输信号调节副边谐振补偿电容的容值进行信号调制,在原边检测电流包络形状特征,进行信号复原。文章分析了副边对原边的反射阻抗对原边电流的影响,并用实验验证了方法的可行性。According to the problem of digital signal reverse transmission in the Inductively Coupled Power Transfer （ICPT） system, a new method for signal reverse transmission based on reflected impedance modulation is pro- posed. This method is implemented to regulate the capacity value of the secondary loop according to the signal transmitted, then monitor the current wave of the primary circuit to demodulate signal. In this paper, how the re- flected impedance influence the current is analyzed and approved by the experimental verification.
